JOHN PAOLI, OF RAHVAY, NEW JERSEY, ASSIGNOR TO THE REGINA MUSIC BOX COMPANY, OF NEW JERSEY.

MUSIC-BOX.

SPECIFICATION forming part of Letters Patent No. 574,758, dated January 5, 1897.

Application filed February 8, 1396. Serial No. 578.474. (No model.)

To ail 2072,0111, it may concern.-

Be it known that I, JOHN PAOLI, a resident of Rahway, Union county, State of New Jersey, have invented certain new and useful Improvements in Music-Boxes, of which the following is a specification.

My invention relates to 1nusic-boxes of that character which employ music-disks to directly or indirectly operate the sound-producing devices, and is an improvement upon the mechanism forming the subject-matter of the invention disclosed in the patent to Braehhausen and Riessner, No. 500,371., dated June 27, 1893.

My said invention consists in the arrangement and combination of parts hereinafter described and claimed for feeding or operating a music-disk from the outer edge.

In the accompanying drawings, Figure 1 is a longitudinal sectional view, on line 1 1 of Fig. 2, of suiiicient number of parts of a music-box to illustrate one form of my invention. Fig. 2 is a transverse section of the same on line 2 2 of Fig. 1.

In the drawings, A represents the bed-plate of the in usic-box, to which is secured a bracket a, pivoted at its upper portion, as indicated at b, to a section 0. In this pivoted section 0 is carried a block (1, which is rendered adjustable by any suitable means, as a thumbscrew 6. \Vithin this block is rigidly fixed one end of a retaining-rod f. Loosely carried upon this retaining-rod is a series of frictionrolls g, suitably spaced upon the red, as by sleeves h, and near one end is carried a gearwheel 2', which is connected with a feed-roll j, which is preferably provided on its periphery with a rubber ring 7;. The periphery of this roll bears upon the note disk or sheet B atits outer edge, as indicated in Fig. 1. Beneath the upper feed-roll j is loosely mounted a feed-roll l, which is preferably constructed like the roll k and is connected in a like manner with a gear-wheel m, which is positively driven by any suitable means, such as from a ring-gear n of the mainspring-drum. The feed-rolls 7c l, together with their respective gear-wheels, are preferably of the same size, so that the surface speed of both feed-rolls will be the same. The note-disk B is provided, in the construction illustrated in the drawings, with pins 0, which may directly or indirectly operate the sound-producing devices.

It will be understood that suitable means are provided'to retain the free end of the rod f against movement when the same is in operative position, so that the friction-rolls 9 will bear upon the plate and hold the same in 0011- tact with the devices to be moved thereby. At the same time the edge of the disk is retained between the feed-rolls 7; Z and is moved forward thereby when the device is put in operation.

It will be observed that by my invention I am enabled to provide a device wherein the feed-rolls exert pressure upon the sheet at diametrically opposite points and that both of such feed-rolls are positively driven at the same rate of speed. Furthermore, it will be observed that by the adjusting means for the rod 1 I am enabled to increase or decrease the amount of pressure exerted by the feed-rolls upon the sheet to compensate for wear upon their peripheries and such other circumstances as the occasions may require.

By driving the disk from the outer edge thereof I am enabled to operate the disk with the exertion of less power and in a steadier and more even manner than could possibly be had when the disk is driven from at or near the center thereof.

In Fig. 2 I have shown a note disk or sheet wherein projections 1) are provided near the edge of the sheet that a better hold may be afforded the feed-rolls. It is obvious that any suitable means may be provided upon the sheet for this purpose. It will be seen, further, that a swinging of the retaining-rodf around its pivot, as indicated in dotted lines in Fig. 1, will not only throw the upper feedroll out of operation but will also throw the gear-wheel i out of operation.

What I claim, and desire to secure by Letters Patent, is

In a m usic-boX, the combination of a musicdisk, a lower positively-driven feed-roll with the periphery thereof bearing upon the disk only at or near the outer edge thereof, a gearwheel formed integral with the feed-roll, means to rotate said gear, a second feed-roll of the same diameter as the first-mentioned l i I their gear-wheels being maintained against movement away from ouch other, whereby when the shaft is turned upon its pivot the upper feed-r011 and gear therefor are thrown out of operation and whereby the pressure oi. the rolls upon the disk or sheet can he regulated.
